9 High-level calculations

After the reduction of raw data (for example, with the programs in Data manipulation) you will have reduced images/data ready for processing/analyzing (for example, with the programs in Data analysis). But the processed/analyzed data (or catalogs) are still not enough to derive any scientific result. Even higher-level analysis is still needed to convert the observed magnitudes, sizes or volumes into physical quantities that we associate with each catalog entry or detected object which is the purpose of the tools in this section.
